Introduction: Sexual dysfunctions are a high prevalence health problem, making it necessary to provide assessment instruments adapted to the Portuguese population.
Methods: The purpose of this study was to validate the Massachusetts General Hospital-Sexual Functioning Questionnaire (MGH-SFQ) for the Portuguese population. Participants in this study were 1079 Portuguese adults who completed a sociodemographic questionnaire and the MGH-SFQ. The participants' ages varied between 18 and 89 years of age (M = 29.66; SD = 13.05), and 32.6% (n = 352) were men and 67.4% (n = 727) were women.
Results: The Cronbach's alpha obtained was .91 and the psychometric properties of the scale were adequate. The validation of the construct was evaluated through Confirmatory Factor Analysis, setting up a suitable one-dimensional model (RMSEA = .041, CFI = .974).
Discussion: Taking into account the results of the psychometric validation, the sample size and the applicability of this instrument in clinical and sexological practice, we can confirm that this is a valid and reliable instrument to evaluate the sexual functioning of both Portuguese men and women.
